Riegens adapts lighting fittings to include return-air path

Riegens lighting
Lighting and a return air path are provided by bespoke Riegens lighting fittings in this London refurbishment project.

Lighting for the prestigious office development at 33 Cavendish Square in London’s West End is provided by Riegens slim-line flush-mounted luminaires with an integrated return-air path.

The depth of the ceiling void averages 285 mm and accommodates a very slim 4-pipe fan-coil system designed by consulting engineers Hilson Moran. The design team recognised the potential of the Riegens Cirrus suspended fitting and asked Riegens to come up with a recessed version with air handling. The bespoke luminaire was developed as a collaboration between ORMS, Hilson Moran and Riegens.

Three floors have been refurbished using DALI luminaires with two 28 W lamps. They have micro-prism panels, dedicated back reflectors and diffuser films to prevent glare. Low-energy lamps and dimmable DALI-controllable ballasts contribute to high energy efficiency.

Hilson Moran comments, ‘We do not believe that a high-level services installation, including both fan-coil units and lighting, has been achieve before in such a shallow ceiling void. The Riegens light fitting, coming in at 55 mm deep overall, played an essential part in achieving this.’
